Claims

[Claims for Utility Model Registration] Rod-shaped lock member 31 and this lock member 31
a guide groove 25 provided in the first housing 2 to guide the axial movement of the lock member 31; and a guide groove 25 provided in the first housing 2 to guide the axial movement of the lock member 31; A locking mechanism for locking the first housing 2 and the second housing 1, comprising a fitting hole 7 provided in the second housing 1 to be engaged with one end of the lock mechanism 31, the locking mechanism being made of synthetic resin. A knob 6 having a width narrower than that of the lock member 31 and a pawl 32 which is held via a beam portion with low bending rigidity are integrally provided on the lock member 31, and the guide groove 25 is provided with this a slot extending from the opening along the axial direction of the guide groove 25 and slidingly contacting the knob 6 to guide the knob 6; a recess into which the pawl 32 of the locking member 31 is loosely fitted; In order to lock the lock member 31, small recesses 33 and 34 are provided on the bottom surface of the recess and are fitted with the arcuate tip 32C of the claw 32, and the lock member 31 is secured to the opening of the guide groove 25. Member 31
When assembling the lock member 31 into the first housing 2 by inserting the lock member 31 from the other end, the lock member 31
The knob 6 is guided into the slot, and the pawl 32 of the locking member 31 is moved back to a position where it slides into contact with the guide groove 25 due to the deflection of the beam, and the locking member 31 is guided into the first slot. After being assembled into the housing 2, the pawl 32 protrudes due to the elasticity of the beam and is fitted into the recess of the guide groove 25, whereby the locking member 31 is assembled into the first housing 2.
A locking mechanism prevents escape from the
